Because polyethylene sheet has many excellent properties, it is widely used in many fields. For example, in the field of construction, polyethylene sheets can be used to make thermal insulation materials, sound insulation materials, moisture-proof materials, etc. Because of its good waterproof performance, it can also be used to make waterproof materials and sealing materials. In the chemical industry, polyethylene sheet can be used to make a variety of containers, pipes, valves, anti-corrosion materials and so on. Due to its good corrosion resistance and chemical stability, it can withstand the erosion of various chemical substances. In the field of agriculture, polyethylene sheets can be made of agricultural films, greenhouse covering materials, irrigation pipes, etc., to improve agricultural production efficiency. In addition, polyethylene sheet can also be used to make medical supplies, packaging materials, wires and cables.

　　High density polyethylene sheet is an important polyethylene sheet, its high density, high strength, good heat resistance, so it has a wide range of applications in many fields. In the field of construction, high-density polyethylene sheets can be used to make road signs for highways, wear-resistant layers for airport runways, waterproof materials for subway projects, etc. Because of its good wear resistance and pressure resistance, it can withstand high-speed friction and heavy pressure. In the chemical industry, high-density polyethylene sheet can be used to make a variety of corrosion-resistant containers, pipes, valves, etc., and can also be used as a lining for anticorrosive materials. In the agricultural field, high-density polyethylene sheet can be made of greenhouse supports, wear-resistant materials for agricultural machinery, etc., to improve agricultural production efficiency. In addition, high-density polyethylene sheet can also be used to make medical supplies, packaging materials and so on.

　　The production process of high density polyethylene sheet mainly includes two ways: extrusion molding and pressing molding. Extrusion molding is the high density polyethylene resin through the extruder heating melt, and then through the mold molding into a certain shape and specifications of the sheet. Press molding is the high density polyethylene resin powder heated above the softening point, and then pressure molding into a certain shape and specifications of the sheet. In the production process, different production processes and formulations need to be selected according to different application needs in order to achieve the best performance and results.

　　The advantages of high-density polyethylene sheet mainly include: high strength and stiffness, can withstand greater pressure and impact; It has good wear resistance, corrosion resistance and aging resistance, and can maintain its performance and service life for a long time. Has good insulation and chemical stability, can be used in different environments and conditions; It has good machining performance and welding performance, and is easy to process and connect.

　　However, high-density polyethylene sheet also has some disadvantages: for example, it is vulnerable to ultraviolet radiation and degradation; Easy to be eroded by certain chemicals; Easy to deform at high temperature; Heavy, not easy to float on the water, etc. Therefore, when using high-density polyethylene sheet, it is necessary to select and use according to its performance and use conditions.

　　In general, high-density polyethylene sheet is an important plastic sheet and has a wide range of application prospects. With the continuous development of science and technology and the emergence of new materials, the performance and application fields of high-density polyethylene sheet will also be further expanded and improved. In the future, high-density polyethylene sheet will be applied in more fields, bringing more convenience and benefits to people's life and work.
